Replacing my agm cell tower batteries

I am a new member as of today, joining to share my experience with the Chevy Volt batteries pictured above. I bought two of them to replace the dead Trojan batteries that were in my 2008 Club Car Precedent golf cart when I bought it a couple months ago, so I have to admit I knew NOTHING about golf carts and NOTHING about Lithium ion batteries when I bought them to power the cart. Long story short, I installed them, tested the cart once (and it drove perfectly), then left it in the driveway for a couple of months while I waited for a properly programmed Schauer charger to arrive.

When I lifted the seat up a couple days ago, I encountered the scenario you see in the photos. One battery was significantly accordioned, the other was horribly so -- I had to gently crowbar it out of the battery compartment, wearing as much protective equipment as I could find. So I have to second Mr. Snoobler's opinion that these are hardly a plug'n'play option for lithium-powered golf cart neophytes like myself. I have them sitting as far away from danger as possible until I can safely dispose of them, and consider myself fortunate that they didn't explode.

And now I'm curious to know if anyone else has had similar experience with these or other Li Ion batteries in other off-label applications. I've searched a popular golf cart forum and found one other instance but with different batteries. I'll be happy to provide what details I can if anyone is interested.

If you were considering $600 for 2 kW lithium batteries,
you could spend $1200 for 5 kWh AGM, SunXtender. Cycle life is supposed to be about 5000 cycles 15% DoD or 500 cycles 80% DoD.
How many kWh do you expect to draw at night? Ideal would be to operate heavy loads during the day while batteries remain full.
I use mine (now a 20 kWh bank) for grid backup so they normally just float. Have so much PV I can run anything in the daytime, with batteries only providing starting surge, everything else from PV.
I think lithium becomes cost effective if it will cycle deeply for 10 years. If cycling is shallow enough that AGM has 10 year life, then it could be cheaper.
